  5. Learning objectives • Diagnose common problems with building HVAC systems and learn how to remedy them. • Learn the proper maintenance of HVAC components including pumps, coils, and valves. • Familiarize yourself with common issues from the field so you can identify and solve them. • Perform walkthroughs and inspections at proper times throughout the year.

  6. Circulatory Systems of Aging BuildingsA Comparison to Human Metabolic Syndrome

  7. Circulation, Ventilation, Pumping, Control Building– Supply and Return Human– Arteries, Veins, and Capillaries Building– Supply/Exhaust Human– Diaphragm/Ribcage Building– Boiler/Chiller Human– Heart Building– EMS Human– Brain

  8. Circulation Building– Supply and Return Human– Arteries, Veins, and Capillaries

  9. Circulation • Basis of Design • Original intent and changes over time. • Comfort vs. Process • Verification • Optimal Performance • Continued Verification • Established Routes- Findings documented and shared. • Significant Events • Modifications and renovations (How many 6” lines can you run off a 6” line?) • Changes to intended operational proceedures.

  10. Ventilation Building– Supply/Exhaust Human– Diaphragm/Ribcage

  11. Ventilation • Basis of Design • ASHRAE and Code Standards • Creaky dampers and frozen ribs. • Optimal Performance • Building pressurization. • Minimum Outside Air. • Stratification. • Significant Events • Work-a-rounds.

  12. Pumping Building– Boiler/Chiller Human– Heart

  13. Pumping • Basis of Design • Push and Pull. • Variable speed. • Tertiary pumping. • Rates of transfer • Optimal Performance • Continued verification. • A thermometer is a Key Performance Indicator (KPI) • Significant Events • Bottlenecks, Bypasses, and Bumbling.

  14. Control Building– EMS Human– Brain

  15. Control • Basis of Design • Occupancy scheduling-Adaptation over years. • Building air balance during unoccupied mode. • Optimal Performance • Communication with occupants. • Event/Alarm Logs. • Cross training through scheduled verification routes. • Significant Events • Power transfer and generator tests. • Overreaction! • WHOA! (Where’s the hand, off, auto?)

  16. Circulation, Ventilation, Pumping, Control A Final Thought – Events That Cause De-Optimization Individual decisions made over time that appear “age-related.”
